A lethargic day + success diet!

Today is one of those days when I wake up and feel that,"oh, I haven't got enough sleep.." and the whole day will go yawning and yawning.. I lost another kg again today. Seems like my strict diet made me lost 5kg in a week.. There's only 1 thing that kept me away from junk food. Self discipline. How I wish this self discipline could also be applied to me restricting myself from watching dramas and convert those times to study usage.. Haix.. Apparently, I intended to study a bit today.. But, I watched an episode then went to pack my books that I don't want to be given away. Then, I am so tired and seemed to be seeing stars already that I cannot stand anymore that I went to have a nap. And there goes my day! No study at all.. Haix.. But, I lost some weight and that's sth to be pleased.. Yawn...
